TO ALL WHQM IT MAY CONGERN Be it known that ADoLrr; PHILIPPI, of Elizabethport, iu the county of Union, and State of New Jersey,

` have invented a new and improved Railroad-Swith Plate; and I do hereby declare that the following is a full,

clear, and exact description thereof, Vwhich will` enable others skilled in the art to make and use the same, reference beinghad to the accompanying drawings, forming part of this specification.

`Figure 1 represents a plan or top view, partly in section,of'my improved switehplate.

Figure 2 is a vertical transverse section of the same, taken on the plane of the line :u :v5 iig. 1. Figure 3 is a vertical longitudinal section of the same, taken on the plane of the line y y, g. l. Similar letters of reference indicate corresponding` parts. This invention relates to'anew'switch-plate, which is so made that the rails have an elastic bearing, and that they can beremoved and replaced at will without'removing the switch-plate. The invention consists et a cast-iron bed, with upward-projecting fianges around all sides, which serve to prevent a wrought-iron plate, and an interposed wooden layer, from sliding olf the bed; andl in arranging a. series of blocks upon the wrought-iron plate, which blocks are shaped similartoia letter T, and serve to holdthe rails down. i

A, in the drawing, represents thecast-iron bed-plate. The same irs of'suitable length, width, and thickness, and from its edges projeet'upward flanges, a a, at the sides, and flanges b .and a at the ends, as shown. Upon the hed A is placed, within the flanges a 6 c, awooden or other elastic plate, B, upon which a wrought-iron plate, C, rests; By means of bolts or rivets, d d, the plates A, B, and are securely fastened to'gethexg'and by' 'means of bolts, e, tothe sleeper, if there is one used. v

Upon the surface of the plate C are secured the rail-holding blocks D and E. 4The outer blocks, D, are shaped, and are, by means of bolts or rivets, f, fastened to the bed and the plates B G, `as shown. llhe inner blocks, E, are T-sliaped, and are, by means of bolts or rivets, g, held in place, as is clearly shown in' fig.

The blocks D rest partly upon the ilanges a, as.y shown, and also abnta-gainst the same, andagainst"a shoulder, h, formed on them, as in iig. 1, and have thus al firm bearing. Still they can,'by taking oil' the bolts or rivets f, be easily removed, so as to allow the removal and replacement of the outer set of rails; and when they are out, the next blocks, E, can also be removed to allow `the removal and replacement of th'e inner rails. From the flanges a vproject inward blocks or lugs, 17, which serve to arrest the switch-bars, to preyent them from moving too far to one side.

I claim as new, and desire to secure byLetters Patent- A switch-plate, consisting of the bed-plate LA, elastic bedB, and plate C, a'nd of the removable blocks D and E, all madefand operating substantially as herein shown and described.

' A. PHILIPPI.'
